When ever you have the chance to encounter a crow in the street close by, take the chance to look into their eyes. There is definitely someone looking back at you!

when a crow finds old bread down the street which has become hard, he will take it to the water, to soak it and get it soft. i have seen it.

A little story:
At the last place I was living, it was usual for the trash bags to be put out on Monday mornings, for the thrash guys to pick up with the truck.
The concierge of our building was a person that did not like getting up early, so she always put the bags on the side walk on the night before.
Crows are scavengers, so they just love to come in a flock and just rip apart the bags and look for treats. But here is the thing. The concierge always put the bags out at the same time (around 6), the crows (who had not been around all week) always arrived already an hour earlier, waiting on the bags
I mean I can see them keeping track of time over the course of a day, or year even, but something totally arbitrary like the 7 day week?!
Mind blown!!!

Crows are the only birds that have been shown to recognize particular individual human beings (instead of reacting to us as a species)
